- Failed external brace therapy defined as either (a) progression of the curve greater than 5 degrees at any time while undergoing external brace therapy, or (b) inability or unwillingness to comply with at least 16 hours per day of external bracing
- Skeletally immature (Risser Sign 0, 1, 2, or 3)
- In girls, either (a) pre-menarchal, or (b) post-menarchal by no more than 6 months

- Candidate for surgical implantation of spinal instrumentation
- Patient resides locally with respect to the Investigator's clinic and is willing and able to comply with the requirements of the protocol
- Must sign informed consent to permit the use of personal health data
You may not qualify if:
